Hydraulic systems play a vital role in power transmission across industries such as manufacturing, construction, agriculture, aerospace, and other sectors where precise and reliable motion control is required. These systems operate by transmitting energy through pressurized incompressible fluid. To support the development and evaluation of individual components, hydraulic test rigs are used, allowing for testing in a controlled environment.
This thesis presents the design of a larger hydraulic test rig, LFT-V25, intended for testing components under high-pressure conditions. Based on analysis and hydraulic calculations, three pumps rated for pressures up to 42 MPa and one for up to 70 MPa were selected, along with a 32-liter hydraulic accumulator, a pressure intensifier capable of reaching 300 MPa, and an appropriate cooling and safety system. The designed configuration enables both functional and load testing at pressures up to 70 MPa with flow rates up to 12 l/min, or up to 300 MPa with flow rates up to 2.5 l/min. Technical catalogs and hydraulic equations were used to verify the adequacy of the solution.
